CAR-ROOF.

Application filed'J'une 8, 1912,

To allwlwm z'tm-ay concern.

Be it known that I, SAMUEL HERBERT, a citizen of the United States of America, re siding at Detroit, in the county of lVayne and State of Michigan, have invented certain. new and useful Improvements in Car- Roofs, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to flexible metallic car roofs of the plate type and consists in the construction as hereinafter set forth.

In the drawings, Figure 1 is a cross section through the roof; Fig. 2 is a longitudinal section in the plane of the ridge purli'n; Fig. 3 is av perspective view showing the relative arrangement of the carlinesandpurlins; Fig. 4 is an enlarged cross section showing the construction of the roof at the caves.

The roof frame is composed of channel beam metallic carlines A preferably extending from eave to eave, and metallic purlins B also preferably formed of metallic channel bars. The carlines A are arranged with the channels opened upward for the purpose of forming drain troughs as will be hereinafter described and are also preferably provided with laterally extending flanges C on opposite sides of the channel. At the eaves the plate D is cut-away on its upper face for the passage of the channel portion of the carl ne which extends through the plate and fascia. The carline is secured preferably by brackets E which are riveted to the lower or web portion of the channel and are secured bv bolts F to the inner face of the plate D. The purlins B are also arranged so that the channels open upward and the side flanges of said channel bars are notched or cut-away at G to receive the channel portion of the carlines and to permit the web portion B of the purlins to lie adjacent to the web portion A of the car-line. The two members are then secured to each other by bolts or rivets H.

The roof frame is covered by metallic sheets or plates which span the spaces between adjacent carlines and are supported so as to be independently movable upon the purlins. These sheets or plates I preferably extend from eave to cave and at their side edges are provided with down turned flanges J which extend into the channels Specification of Letters Patent.

Serial No. 702,467. Renewed May 3, 1916. Serial No. 95,254.

The plane of the body portion of the plate is substantially that of the upper end of the purlin but to prevent the wearing of the plates due to metallic contact, wooden inserts K are placed in the channels of the purlins, said inserts projecting up slightly above the edges of the side flanges of said purlins. Thus the. roof ing plates will rest upon wooden supports. The flanges C of the carlines are slightly above the plane of the body of the sheets I and the latter are bent upward at L so that the portion M above the flanges, C will clear the same. There is also a clearance space N between the bend L and the outer edge of the'flange C and a corresponding clearance space 0 between the flange J and the carline, these clearances permitting of a lateral adjustment of the roofing plate durmg the weaving and other flexing 0f the roof frame.

P are metallic caps covering the carlines and the channels therein and provided with down turned flanges Q which overlap the bends L in the roofing plates. These caps also preferably extend from eave to cave and at their ends are provided with down turned flanges R. The roofing plates I are likewise provided with down turned flanges S, these flanges being secured to the side of the car by suitable means such as bolts T secured to the fascia and passing outward through the flanges. The flanges R and S are spaced from the fascia and are sleeved upon thimbles U on the bolts T.

With the construction as thus far described the caps P with their down turned flanges Q, will protect the channels from direct access of the rain and such water as is driven through the joint between the caps and the sheets into the channel will drain down through the latter to the sides of the car. Inasmuch however, as the web of the carlines is perforated for the bolting or riveting of the same to the purlins and the brackets E, the channels are not water tight and consequently would permit leakage into the car. This I have avoided by placing a liner V within the channel which has upturned flanges V overlapped by the down turned flanges J of the plates, while the center or web portion is bent upward at V to provide clearance for the bolt or rivetheads. This liner extends to the caves and of the carlines.

at th ridge is secured by a bolt W which passes through the ridge purlin, carline, the liner, a supporting block X, the cap P and the saddle block Y, all of said parts being secured by the one bolt.

The roof constructed as described will be thoroughly weather proof as any water finding access to the channel will drain out through the liner trough. At the same time the roof is permitted to fiex without strain or distortion of the roofing plates which are free to relatively adjust any compensation for any distortion of the roof frame. Nhat I claim as my invention is:

1. The combination of an upturned channel carline having an apertured web portion, securing devices passing through the apertures in said web, a roofing plate having a down turned flange engaging the channel, and a trough-shaped liner for said channel covering said securing device.

2. In a car roof, the combination of an apertured channel carline, headed bolts passing through apertures in the web of said carhne, a roofing plate having a down turned flange engaging the channel of said carline, a cap for said channel and a troughshaped liner for said channel bent upward to provide clearance for said headed bolts and forming a drainage channel to the cave of the car.

3. In a car roof, the combination with a carline formed of an upturned channel beam having laterally-extending flanges, of a purlin formed of an upturned channel beam intersecting said carline, the tops of the flanges of said purlin being in substantially the same plane as the laterallyeXtending flanges, a roofing plate adjacent to said carline having a down-turned flange entering the channel thereof, and a waterproof trough-shaped liner for said channel Within the same and overlapped by the down-turned flange of said plate.

In testimony whereof I affix my signature in presence of two witnesses.
